Step 8: 6489 + 927 = 7416
Step 9: 7416 + 927 = 8343
Step 10: 8343 + 927 = 9270
Step 11: 9270 + 927 = 10197
Step 12: 10197 + 927 = 11124
Step 13: 11124 + 927 = 12051
Step 14: 12051 + 927 = 12978
Step 15: 12978 + 927 = 13905
Step 16: 13905 + 927 = 14832
Step 17: 14832 + 927 = 15759
Step 18: 15759 + 927 = 16686
Step 19: 16686 + 927 = 17613
Step 20: 17613 + 927 = 18540
Step 21: 18540 + 927 = 19467
Step 22: 19467 + 927 = 20394
Step 23: 20394 + 927 = 21321
Step 24: 21321 + 927 = 22248
Step 25: 22248 + 927 = 23175
Step 26: 23175 + 927 = 24102
Step 27: 24102 + 927 = 25029
Step 28: 25029 + 927 = 25956
Step 29: 25956 + 927 = 26883
Step 30: 26883 + 927 = 27810
Step 31: 27810 + 927 = 28737
Step 32: 28737 + 927 = 29664
Step 33: 29664 + 927 = 30591
Step 34: 30591 + 927 = 31518
Step 35: 31518 + 927 = 32445
Step 36: 32445 + 927 = 33372
Step 37: 33372 + 927 = 34299
Step 38: 34299 + 927 = 35226
Step 39: 35226 + 927 = 36153
Step 40: 36153 + 927 = 37080
Step 41: 37080 + 927 = 38007
Step 42: 38007 + 927 = 38934

So, 927*42 = 38934
